Zentrum für Technomathematik Fachbereich 3 – Mathematik und Informatik Nonlinear Inverse Unbalance Reconstruction in Rotor dynamics

Abstract

This paper is devoted to the identification and reconstruction of unbalance distributions in an aircraft engine rotor with a nonlinear damping element. We have developed a rotor model that takes into account the nonlinear behavior of a squeeze film damper between the engine’s shaft and casing for large oscillation amplitudes. Based on the Tikhonov… (More)
